ABSTRACT:
A light waveguide with a high tensile strength including a light conducting or optical fiber being coated with a plastic coating to improve the tensile strength characterized by the plastic coating being a plastic lacquer applied directly on the surface of the light conducting fiber, being a high temperature stable material selected from a group consisting of polyurethanes, epoxides, polyesters, polyesterimides, polyimides, and polyvinyl dimethoxymethane, which material has a softening temperature of at least 150.degree. C. The coating has a thickness of at least 2 .mu.m and is uniformly concentrically applied over the entire length of the light conducting fiber without any surface defects. The light waveguide may include an outer covering which is either tightly applied or loosely applied onto the light conducting fiber and its coating. To improve movement of the light conducting fiber and its coating in the covering, a slide layer may be interposed between the outer covering and the plastic lacquer coating.
